Cloudflare DNS and image cdn in front of Netlify

Currently I have disabled accelerate and protect in Cloudflare due to the recommendation in this forum post:

I am using Cloudflare just for DNS right now, and Netlify’s image cdn by prepending “/.netlify/images?url=/” to all of my images. Netlify’s image CDN seems pretty slow, and I’d like to use Cloudflare instead. Am I going to receive the same penalties mentioned in the article above from the forums if I do this?

Is there a recommended way of doing this?

I don’t think adding Cloudflare here would make any significant differences in speed to be honest. The only benefit Cloudflare might provide you is an additional cache layer, so for the situations where Cloudflare has the image cached, it would be a little faster. But outside of that, Cloudflare or not, you’d likely get the same performance.
